Typical Cost in Markham
$150–$500
Final cost depends on severity, property size, and treatment method.
Markham has two pest realities separated by about 30 years of construction. Walk down Main Street Unionville and the heritage homes there have fieldstone foundations with gaps that mice have been using since before the town had a traffic light. Drive 15 minutes north to Cornell or Box Grove and the brand-new detached homes are already getting mice through settling gaps around gas lines and dryer vents — the foundation shifts in the first two winters and opens up entry points the builder never sealed. The Rouge River cuts through eastern Markham and delivers raccoons, skunks, and squirrels right into the backyards along Rouge River Estates. Milliken is rat territory — the dense mix of restaurants and food businesses along Steeles and McCowan feeds Norway rat populations that burrow under adjacent residential foundations. Angus Glen looks pristine, but the golf course is raccoon habitat and they do not stay on the fairways.
Our Wasp Removal Process in Markham
Inspection
The technician locates the nest, identifies the species, and evaluates the size. Yellowjacket ground nests and wall-void nests are harder to find — the tech follows flight patterns to trace the entry point.
Treatment
Professional insecticide dust is injected directly into the nest entrance. The dust clings to wasps as they exit and enter, spreading through the colony including the queen. This eliminates the entire colony within 24–48 hours. Ground nests get treated through the entry hole; aerial nests are treated and removed.
Prevention
A residual product applied around the nest site eliminates returning foragers over the next 24–48 hours. For wall-void nests, the entry hole is sealed after treatment to prevent future colonies from using the same access point. The technician checks for other potential nesting sites around the property.
Signs You Need Wasp Removal in Markham

-
A visible paper nest under eaves, porch ceilings, deck railings, or in a tree
-
Aggressive wasp behaviour when you walk near a certain area of your yard or house
-
Buzzing sounds inside a wall, soffit, or attic space — indicates a wall-void nest
-
Increasing wasp numbers at your outdoor eating area, especially in late August and September
Why Hire a Professional in Markham
-
A disturbed wasp nest sends the entire colony into attack mode. Unlike bees, wasps sting repeatedly. For anyone with allergies, this is a medical emergency.
-
Wall-void nests are invisible from outside. Spraying the entry hole drives wasps deeper into the wall or into the living space through gaps around outlets and light fixtures.
-
Yellowjacket ground nests can contain 1,000+ wasps by late summer. A professional treats the colony at the source with insecticide dust injected directly into the nest cavity.
-
Over-the-counter wasp sprays have limited reach and no residual effect. Professional products continue killing for days.
-
Most GTA pest control companies offer same-day wasp removal. A wasp nest near a front door or kids' play area is a genuine safety hazard that should not wait.
